Ideal Weight Calculator (Metric)

What is Ideal Weight?

Ideal weight is the optimal body mass that corresponds to your height and gender, promoting the best health outcomes. Our calculator uses the scientifically validated Devine formula to determine your ideal weight.

How the Ideal Weight Calculator Works

The calculator employs the Devine formula, developed in 1974:

• For men: 50 kg + 2.3 kg × (height in inches - 60)
• For women: 45.5 kg + 2.3 kg × (height in inches - 60)

This formula accounts for physiological differences between men and women and is widely used in medical practice for determining target body weight.

Healthy Weight Ranges and BMI Categories

Beyond ideal weight, it's important to understand healthy weight ranges for your height:

• Underweight: BMI below 18.5
• Normal weight: BMI 18.5-24.9
• Overweight: BMI 25-29.9
• Obese: BMI 30 and above

Factors Affecting Ideal Weight

When determining your target weight, consider:

• Body frame size (small, medium, large)
• Muscle mass and activity level
• Age and health status
• Genetic factors and metabolism
